Cloud API vs Coexistence vs Personal WhatsApp

Three options for different business needs

There is no single best option for everyone. Your ideal setup depends on whether you need the phone app, official API infrastructure, rapid setup or advanced automation.

Simple guidance

Which option should you choose?

Choose Cloud API Only if…

You want a dedicated official business number, do not need the mobile app and expect API-led automation to be your main operating model.

Choose Coexistence if…

Your team needs to keep using an eligible WhatsApp Business app number while adding official Cloud API automation and integrations.

Choose Personal Device if…

You want a quick, lower-barrier connection for lighter usage and accept that it is device-session based rather than an official Cloud API connection.

Before choosing Coexistence: Meta determines eligibility and may change supported countries, account requirements and feature behaviour. Chat history and message synchronisation can also depend on the onboarding permissions and supported Meta behaviour. Contact WebWMS2U if continuity of particular conversations or workflows is essential.
